Models:

74S: Standard, basic design 74D: Digital meters 74DX: Deluxe — digital, full-feature Toolless rotatable drive assembly allows operator to rotate the drive housing, eliminating severe bends in the wire feed path which reduce gun liner life. Also aids in feeding difficult wires.

S-74D Model

S-74DX Model Easy access on/off switch

Trigger receptacle oriented in a downward position to reduce potential damage. Trigger hold reduces operator fatigue by allowing the operator to make long welds without having to energize the trigger continuously. Automatic run-in control significantly improves arc starting performance. Posifeed™ Wire Drive Assembly Features 24 VDC high-torque, permanent-magnet motor. Quick-change drive rolls. Quick-release, calibrated drive-roll pressure adjustment arm allows drive roll change without losing spring preload setting. Four sealed ball bearing all-gear-driven drive-roll carriers for smooth, positive and accurate wire feed with long uninterrupted service life. Easy loading and threading of welding wire without having to release the drive-roll pressure arm. Solid-state speed control and brake circuit eliminates the need for electrical/ mechanical relays and increases service life. Uses Miller standard 1-5/8 in (41 mm) diameter drive rolls. Quick-connect for all Miller guns. Covered drive rolls — easy access, heavy-duty, molded composite cover over drive assembly. Floating positive drive systems provide trouble-free feeding on a variety of wires.

10 ft, 14-pin interconnecting cord for the operator to hook up.

Dual tension control adds flexibility for the operator to fine-tune the pressure on the wire independently when feeding a variety of wires.

DX Models Additional Features Dual schedule allows operator to switch between two welding parameters without readjusting machine, eliminating downtime and enhancing quality. Adjustable weld sequence control gives operator complete control of the welding parameters: preflow, run-in, weld time, crater, burnback and postflow. Welding process range control locks parameters at a set percentage of welding parameters to ensure welding procedures and quality standards are maintained on the shop floor. Four weld programs allow the operators to store four independent welding parameters reducing welding setup time. (Four programs available per side on dual model.)

Wire feeder is warranted for 3 years, parts and labor.
